What this site does
ARPG Build Tools helps players test whether the Spirit, reservation, and minion assumptions from a build guide actually fit their character before they finalize gear or skill choices.
What this site does not do
The site is not a complete build ranking portal and does not try to replace experienced build creators. It focuses on narrow checks that are easy to miss when a setup is copied, adapted, or revisited after a patch.
Editorial approach
The site is designed around practical validation tools first. Guides should explain assumptions, formulas, failure cases, and patch-sensitive values, then route players back into a checker or preset they can use.
